Notes:
Compiler: Phase diagram indicates formation of a 1:1 fluorene - 2,4,6-trinitromethylbenzene molecular compound melting at about T/K = 358.5. Two eutectic points occur at about x
1
= 0.22 and T/K = 345.5, and at x
1
= 0.71 and T/K = 353.
Method/Apparatus/Procedure:
Binary mixtures prepared by weight. While the experimental details were not given in the paper, compiler speculates (based upon quantity of material used) that the sample was sealed in a glass container, temperature slowly varied, and the phase diagram determined by visually noting the temperature at which the last/first crystal of solid disappeared/appeared.
Source and Purity of Materials:
(1) Purity and chemical source were not specified in paper.
(2) Purity and chemical source were not specified in paper.
Estimated Errors:
Temperature: T/K: precision ± 0.2 (compiler). x

: ± 0.002 (compiler).
